Such a device is known for example from the Austrian utility model AT 8882 U1. In the device shown there, the two locking units are arranged at the rear end of the drawer and coupled to each other via a torsion bar. The disadvantage here is the additional space required in the depth of the furniture has been found. In addition, results from the coupling of the two locking units by means of the torsion bar tends tilt the front panel.

From EP 1 314 842 A1, a synchronization unit protrudes in the front region of the underside of the drawer. Since this synchronization mechanism is very large, this would find no place at the back of a drawer. In addition, the execution of the synchronization unit or the linkage with a rack, a gear and a release lever is relatively complicated. There is no rotational movement of these linkage components which could be converted into an ejection movement of a Ausdrückhebels.

Based on this prior art, it has the object of the invention to provide a generic device that avoids these disadvantages and also allows easy maintenance and adjustment.

According to the invention, this object is achieved by at least two locking units via a synchronization mechanism having at least two, each different locking units associated coupling elements and at least one synchronization unit, are in operative connection with each other, wherein the coupling elements are coupled by means of the synchronization unit achieved.

In Fig. 1, a piece of furniture 1 with a movably mounted therein furniture part 2 is shown in general. In this case, the opening of the movable furniture part 2 formed by a drawer takes place via a touch-latch mechanism, i. the user presses the movable furniture part 2 by exerting force on the handle-less front panel 3 from a closed end position E in the closing direction SR of the movable furniture part 2 by a predetermined distance further into the furniture 1, whereby the locking of an ejection device is released and the movable furniture part 2 means the ejection device is extended into an open position from the furniture 1. FIGS. 2 a and 2 b show sections of a bottom view of a furniture part 2 movably mounted in a furniture 1. In this case, the movable furniture part 2 is movable by means of a drawer rail 23 in an am Furniture carcass 4 of the furniture 1 fixedly arranged cabinet rail 13 movably guided. On the underside 25 of the movable furniture part 2, a locking device 5 for locking the movable furniture part 2 in a closed end position E is arranged in the region of the front panel 3. The locking device 5 comprises a locking unit 6 with a receiving element 7, which is at least in the closed end position E with a stationary on the carcass rail 13 arranged engagement member 8 is engaged.

In order to be able to change the front gap F, which corresponds to the distance between the front panel 3 and the furniture body 4 with the end position E of the movable furniture part 2 closed, and thus the triggering path for the touch-latch mechanism, in the embodiment shown in FIG 2a and 2b, the receiving element 7 for the engaging element 8 arranged on a linearly mounted in a base part 11 of the locking unit 6 sliding part 10 and the locking unit 6 has an adjusting device 9, by means of the relative position of the receiving element 7 to the engagement element 8 in the depth of Furniture 1 is changeable, up.

The adjusting device 9 is designed to convert a rotational movement into a translational movement and has for this purpose a rotatably mounted actuating element 12, whose axis of rotation f is substantially normal to the main plane of the locking unit 6 and in the embodiment shown directly to the linearly movably mounted sliding part 10 acts.

Starting from the position shown in Fig. 2a with the front gap F between the front panel 3 and the furniture body 4 and the distance A between the sliding part 10 and the base part 11 of the locking unit 6 can therefore by turning the actuating element 12 of the adjusting device 9 the relative position of the receiving element 7 to the engagement element 8 are changed so that, as shown in Fig. 2b, a larger front gap F 'and a smaller distance A' between the sliding part 10 and the base part 11 of the locking unit 6 results. Of course, this change in position of the receiving element 7 to the engagement element 8 can take place in both directions, wherein the value of the front gap F, F 'to the value of the distance A, A' is inversely proportional, i. If the front gap F, F 'becomes larger, the distance A, A' between the sliding part 10 and the base part 11 decreases to the same extent, and vice versa. By this advantageous embodiment of the locking device 5 and the arrangement thereof on the bottom 25 of the movable furniture part 2 in the front panel 3, the user can change the front gap F, P and thus the position of the movable furniture part 2 in the closed end position E without tools in a simple manner or adjust.

The furniture body 4 to be arranged or arranged carcass rail 13 is shown in Fig. 3. On the carcass rail 13, the engaging member 8 and the rear end portion of an ejector 18 is disposed in the rear end portion, wherein the mounting of the carcass rail 13 in the furniture 1 takes place such that the engagement element 8 is located in the front of the furniture front.

4, the ejection device 18 is shown in an exploded view, which in the illustrated embodiment, a two-part housing 21, 21 ', in which an acted upon by a force storage device 19 ejector 20 is movably mounted with a stop 22 formed thereon. The locking of the ejection device 18 takes place in this embodiment via the engagement element 8, which is locked in the closed end position of the movable furniture part 2 by means of the receiving element 7 of the locking unit 6. After unlocking the ejector 18, that is, when the engagement member 8 is released from the locking unit 6, the energy accumulator 19 discharges and moves in this way the ejection element 20, its movement over the stop 22 on the drawer rail 23 or directly on the movable furniture part 2 is transmitted. The engagement element 8 shown in FIG. 5 has a plate-shaped base element 14, which can be positively connected to the carcass rail 13 via the latching head 17 formed on an extension 16, or connected is. In the latching head 17 opposite end portion of the engaging element 8, a pin 15 is arranged on the plate-shaped base member 14, the longitudinal axis L is substantially normal to the main plane of the base member 14. When the end position E of the movable furniture part 2 is closed, the engagement element 8 engages via the pin 15 in engagement with the receiving element 7 of the locking unit 6, whereby on the one hand the movable furniture part 2 is locked in its closed end position E and on the other hand the ejection device 18 is locked.

Fig. 6 shows an oblique view of the underside of a movable furniture part 2. In this case, the movable furniture part 2 is formed by a drawer, wherein on the bottom 25 in the front panel 3, a locking device 5 is arranged. The locking device 5 has two locking units 6, which are coupled by means of a synchronization mechanism 24. Both locking units 6 each have a receiving element 7, which are in each case with a arranged on the two body rails 13 engagement element 8 in engagement. The movable furniture part 2 is movably mounted in the carcass rail 13 via a drawer rail 23.

In the Fig. 7a and 7b, the embodiment of FIG. 6 in two different positions of the movable furniture part 2 is shown. In this case, FIG. 7 a shows the movable furniture part 2 in the closed end position E and the two receiving elements 7 of the locking units 6 engage with the engagement elements 8 arranged on the carcass rails 13. The coupling of the locking units 6 by means of the synchronization mechanism 24 via coupling elements 26 which are rod-shaped in the embodiment shown and at one end pivotally connected to the receiving elements 7 and at its other end pivotally connected to the synchronization unit 27.

If, starting from the closed end position E shown in FIG. 7a, the movable furniture part 2 is pressed into the furniture carcass 4 by a force exerted on the front panel 3 in the closing direction SR, the locking mechanism 31 is released and the locking between the receiving elements 7 and the engagement elements 8 are released, so that the receiving elements 7 are pivoted from their shown in Fig. 7a second, the engagement member 8 arresting position Si by means of the ejection device in a second, shown in Fig. 7b, the engagement member 8 releasing position s2.

By the coupling of the two arranged on opposite sides of the movable furniture part 2 locking units 6 via a synchronization mechanism 24 ensures that the lifting of the lock and thus the triggering of the ejector substantially simultaneously takes place, regardless of where at the front panel. 3 the user applies the necessary release force in the closing direction SR of the movable furniture part 2.

For this purpose, the synchronization mechanism 24 has a synchronization unit 27, wherein the receiving elements 7 of the locking units 6 are connected to the synchronization unit 27 via coupling elements 26 which are coupled in opposite directions by means of the synchronization unit 27 in opposite directions.

In the embodiments shown in Fig. 7a and 7b, after releasing the locking mechanism 31, the receiving element 7 shown in the picture on the right pivoted by the extension movement of the movable furniture part 2 to the right and pulls on the coupling element 26, the rack 30 of the synchronization unit 27 also to the right. The second rack 30 of the synchronization unit 27 is shifted to the left in the image via the synchronization element 29 formed by a gearwheel in the illustrated embodiment, whereby the coupling element 26 shown on the left of the image moves in the opposite direction via the synchronization unit 27 from right to left and moves the left receiving element 7 forward is pivoted to the left. In the opposite sense, motion-coupled means in the illustrated embodiment both a reversal of the direction of movement and a change between tensile and shear force.

Fig. 8 shows a further embodiment in which the locking units 6 additionally have an overload-locking mechanism 32, which allows a damage-free opening of the movable furniture part 2, even if the receiving element 7 by means of the locking mechanism 31 in a second engagement element arresting position S! is fixed.

For this purpose, as shown in Fig. 9a, the receiving element 7 is formed in two parts, wherein the base member 43 and the locking member 44 are rotatably connected to each other and the locking mechanism 31 acts on the base member 43. The base member 43 and the locking member 44 of the receiving element 7 form in this embodiment, the two rotatable with each other, pivotable between a first and a second end position parts of the overload-locking mechanism 32, wherein between the base member 43 and the locking member 44, a holding device 33 acts. The operation of the overload-securing mechanism 32 will be explained in more detail with reference to Figs. 30a to 30g.

In the positions shown in FIGS. 9a and 9b, the movable furniture part 2 was opened by applying the release force to the front panel 3 in the closing direction SR (FIG. 9a), whereby the locking mechanism 31 is released and a triggering of the overload Securing mechanism 32 is not necessary. Incidentally, the embodiment shown in Figs. 9a and 9b corresponds to the embodiment of FIG. 7a and 7b, which is why a further detailed description is omitted.

A first preferred embodiment of a synchronization unit 27 is shown in perspective in FIG. The synchronization unit 27 comprises a base element 28 on which a synchronization element 29 is rotatably mounted. In the embodiment shown, the synchronization element 29 is formed by a gear and are on the base member 28, two racks 30 on opposite sides of the synchronizing element 29, in the same engaging, mounted in the guide tracks translationally movable.

11a and 11b show in a plan view two different positions of the synchronization unit 27 according to FIG. 10. Starting from the position according to FIG. 11a, the two toothed racks 30 are displaced in opposite directions during pivoting of the receiving elements 7 of the locking units 6 (FIG. 11b), wherein the opposite movement of the racks 30 is coupled via the rotating synchronization element 29 and synchronized.

For fixing the synchronization unit 27 on the movable furniture part 2, the base element 28 has passage openings 34, which are formed in the embodiment shown in the form of elongated holes on. The connection of the synchronization unit 27 with the coupling elements 26 via receiving openings 35 which are formed in the outer end portions of the racks 30.

Another embodiment of a synchronization unit 27 is shown in FIGS. 12 to 14b. The synchronization unit shown in perspective in FIG. 12 differs from the exemplary embodiment according to FIG. 10 in that the base element 28 is designed in two parts. As can be seen in FIG. 13, which shows an exploded view of the exemplary embodiment shown in FIG. 12, the base element 28 has a base element 41 and an intermediate element 42, wherein the synchronization element 29 and the two toothed racks 30 are arranged on the intermediate element 42.

In this embodiment, the base member 41 has two passage openings 39 for receiving fastening means 36, with which the base member 41 is fixed to the movable furniture part 2, on. The receiving openings 40, which are likewise arranged on the base element 41, serve for fastening the intermediate element 42 to the base element 41. For this purpose, elongated holes 34 are arranged on the intermediate element 42, in which case the fastening of the intermediate element 42 to the base element 41 via the Austrian Patent AT506 542 B1 2012-12-15 a guide pin 38 and a fastener 37 takes place.

By this design it is avoided that the racks 30 and the coupling elements 26 by the screwing of the base member 28 on the bottom 25 of the movable furniture part 2, for example, on the shelf of a drawer, brace. Due to the two-part design of the base member 28, the base member 41 can be mounted on the bottom 25 of the movable furniture part 2 in a first step, wherein the fastening element 37 formed by a clamping screw for locking the intermediate element 42 is first released and only after the assembly of the synchronization unit 27th is attracted to the movable furniture part 2 in a further step, which allows a substantially stress-free installation of the synchronization unit 27.

FIGS. 14a and 14b show two different mounting positions of the synchronization unit 27 according to FIG. 12, the basic element 41 and the intermediate element 42 according to FIG. 14b and, according to FIG. 14a, the intermediate element 42 with respect to the base element 41 is shifted to the right.

The embodiment shown in Fig. 15 differs from the embodiment of FIG. 9a in the formation of the synchronization unit 27. As can be seen in particular from Figs. 16a and 16b, the synchronizing element 29 is formed in this embodiment of a two-armed lever, the In its two opposite end portions receiving openings 35 for connection to the coupling elements 26 has.

The synchronization element 29 is in turn mounted rotatably on the base element 28. As in the above-described embodiments, the movements of the receiving elements 7 are transmitted via the coupling elements 26 to the synchronization unit 27, however, in this embodiment, the coupling elements 26 are connected directly to the synchronization element 29. As in the embodiments with two racks 30 and a gear, the two coupling elements 26 are in this case in opposite directions motion coupled via the synchronizing element 29 formed by a two-armed lever in this embodiment.

A locking device 5, in which the two locking units 6 via a synchronization mechanism 24 having a synchronization unit 27 and two coupling elements 26 are coupled together synchronously, is in Fig. 17a in a plan view from above and in Fig. 17b in one Skew view shown from below. In this case, the synchronization element 29 of the synchronization unit 27 is formed by a two-armed lever.

The locking unit 6 according to the embodiment of FIGS. 17a and 17b is shown in Fig. 18 in an exploded view. The attachment of the locking unit 6 on the movable furniture part 2 via the base part 11, in which a sliding part 10 is arranged to be linearly movable. The change in the position of the sliding part 10 with respect to the base part 11 via an adjusting device 9, which has an actuating element 12. The actuating element 12 is rotatably mounted on the base part 11 about the axis of rotation f and has on its side facing the sliding part 10 a spiral guide track, not shown, which is operatively connected to the sliding part 10 arranged guide means 47, ie, a rotation of the actuating element 12 causes a linear Displacement of the sliding part 10.

On the sliding part 10, the receiving element 7 is rotatably supported about the axis of rotation d, wherein in the embodiment shown, the receiving element 7 is formed in two parts and a rotatably mounted base member 43 and a pivotally connected to the base member 43 locking member 44 has. The base member 43 and the locking member 44 simultaneously form the two pivotally connected parts of an overload mechanism 32 and are connected to each other via a holding device 33 formed by a tension spring.

The locking mechanism 31 for locking the receiving element 7 in a position Si arresting the engagement element 8 comprises in the illustrated exemplary embodiment an Austrian patent office AT 506 542 B1 2012-12-15

Sliding link 45 and acts between the linearly movable sliding part 10 and the rotatably mounted thereon, acted upon by a spring 46 receiving element. 7

Another embodiment of a locking unit 6 is shown in an exploded view in Fig. 19a and in a perspective view in Fig. 19b. The embodiment of FIG. 19a and 19b differs from the embodiment of FIG. 18 only by a different shape of the parts. The operation of the locking unit 6 corresponds to the operation according to the above-described embodiment, which is why a further detailed description is omitted.

FIGS. 20a and 20b each show a locking unit 6 according to FIG. 19b arranged on a movable furniture part 2, wherein the locking unit 6 engages in each case with the engagement element 8 and via a coupling element 26 which is part of a synchronization mechanism 24. with a second, arranged on the opposite side of the movable furniture part 2 locking unit 6 is coupled in motion.

In this case, starting from the position shown in Fig. 20a by rotating the actuating element 12 of the adjusting device 9, the front gap F or the distance A between the sliding part 10 and the base member 11 is changed, resulting in a larger front gap F 'and a smaller Distance A 'results (FIG. 20b), ie. the position of the movable furniture part 2 in the furniture body 4 in the depth of the furniture 1 can be adjusted by turning the actuating element 12 of the adjusting device 9 in a simple manner by the user.

In the embodiment shown in Figs. 21a to 22b, the two rotatably connected parts of the overload-securing mechanism 32 are in turn formed by a base member 43 and a locking element 44 of a receiving element 7. In contrast to the exemplary embodiments according to FIGS. 18 and 19, in this exemplary embodiment the holding device 33 is designed in two parts, one part 50 being arranged on the locking element 44 and the second part 51 being arranged on the base element 43. In this case, the first part 50 of the holding device 33 is designed as a latching head and the second part 51 of the holding device 33 as a latching receptacle, so that the holding device 33 acts positively.

Fig. 21a shows the embodiment in perspective in an open position of the holding device 33, Fig. 21b is an exploded view of the holding device 33 of FIG. 21a. 21a shows the arrangement principle of the exemplary embodiment according to FIG. 21a in a plan view and indeed with the holding device 33 closed. That is, the movable furniture part 2 is in its closed end position E, so that the locking element 44 locks the pin 15 of the engagement element 8. Now, if the movable furniture part 2 is pulled by the user in the opening direction OR, without the locking mechanism 31 is previously canceled by pressing the movable furniture part 2 in the closing direction SR, opens the holding device 33 by the force exerted by the pin 15 on the locking member 44 , That is, the positive connection between the parts 50 and 51 is released and the movable furniture part 2 can be brought into an open position without the receiving element 7 is damaged.

The embodiment shown in FIGS. 23a to 24b of a receiving element 7 with a locking mechanism 32 functions analogously to the exemplary embodiment shown in FIGS. 21a to 22b. The embodiment according to FIGS. 23 a to 24 b differs from the exemplary embodiment according to FIGS. 21 a to 22 b in the manner of the two parts 50, 51 of the holding device 33. In this embodiment, the two parts 50 and 51 of the holding device 33 are formed by two magnets, which to have an attractive effect on each other.

By moving the movable furniture part 2 in the release position of a slide track 45 formed locking mechanism 31 is released, whereby the base member 43 is pivoted so that the pin 15 of the engagement element 8 is released from the locking element 44 (Fig. 29c) and the movable furniture part 2 by means of the ejection device in an open position, as shown in Fig. 29c, driven. In FIGS. 30a to 30g, different positions of the receiving element 7 of the locking unit 6 according to the exemplary embodiment according to FIG. 20a are shown in the case of a maloperation by a user. An incorrect operation is understood to mean that the user pulls out the movable furniture part 2 from the furniture body 4, without previously lifting the locking of the engagement element 8 by the receiving element 7 by pressing the movable furniture part 2.

In this case, Fig. 30a shows again the starting position, in which the movable furniture part 2 is in its closed end position E. If, as shown in Fig. 30b, the movable furniture part 2 is pulled directly in the opening direction OR, the locking element 44 of the receiving element 7 is rotated or pivoted about its axis of rotation e due to its contact with the pin 15 of the locking element 8 and against the force of in this embodiment, a holding device 33 formed by a tension spring.

In Fig. 30c, the pin 15 of the engaging member 8 has already left the receiving portion 48 of the locking element 44, whereby the locking element 44 by means of the holding device 33, that is, by the relaxing tension spring, swung back again (Fig. 30d). In this position, therefore, the movable furniture part 2 is in an open position, wherein the locking mechanism 31 is not canceled for the base member 43.

If, as shown in FIG. 30e, the movable furniture part 2 is moved into the furniture body 4 in the closing direction SR, the locking element 44 moves onto the journal 15 and, as the movable furniture part 2 moves in further, becomes the receiving element 7, as in FIG Fig. 30f shown, pivoted, whereby the locking mechanism 31 is released and the base member 43 is pivoted due to the relaxing spring 46 in a pin 15 releasing position, whereby the movable furniture part 2 of the ejection device 18, the energy storage 19 by the Hineinbewegen of movable furniture part 2 was at least partially loaded, again in an open position (Fig. 30g) is moved.

The open position according to FIG. 30g after an incorrect operation by the user therefore corresponds to the open position according to FIG. 29d after a normal opening operation. In other words, in the event of misuse by use in a first step, the overload safety mechanism 32 comes into play, whereby the movable furniture part 2 - although the locking unit 6 has not been unlocked - can be opened without parts of the locking unit 6, in particular the receiving element 7, be damaged before the movable furniture part 2 is moved in a second step again in the closing direction SR in the furniture body 4. If then the receiving element 7 abuts the pin 15 of the engaging element 8, the locking mechanism acting on the locking unit 31 31 is released in a third step, whereby in a fourth step, the movable furniture part 2 is again guided in an open position due to the spring-loaded receiving element 7. In other words, the movable furniture part 2 must be closed twice after an incorrect operation, so that it is again in a closed end position E.

The illustrated embodiments of locking devices for locking a movable furniture part and lockable ejection devices for a movable furniture part are of course not to be understood in a limiting sense, but just a few examples of numerous possibilities the inventive idea of a locking device or a lockable ejector for a movable To realize furniture part. 10/26
